· JVASP-29372· NbI2O

NbI2O is an experimental niobium iodide oxide ceramic compound combining niobium, iodine, and oxygen in a mixed-valence structure. This material belongs to the family of rare transition metal halide oxides and remains primarily in research development rather than established industrial production. The compound is of interest to materials scientists exploring novel ceramic phases with potential applications in functional ceramics, given its unique composition bridging refractory metals and halide chemistry.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
